Veins, Arteries and Capillaries

It needs to get oxygen and nutrients from the top to the bottom of your body and it manages this with the help of the body’s circulatory system.

The body has a network of blood vessels that carry blood around.

The way it works is quite similar to how traffic runs on the roads.

To keep traffic running smoothly, all the traffic travelling in the same direction will travel on the same part of the road and the same goes for blood vessels. Arteries travel in one direction, veins in the other.
